Abstract

Heritability of the more important yield components in rice (stem height, number of productive tillers/plant, lenght of the main panicle, number of primary branches/main paincle, number of grains/main paincle, grains mass/main panicle and grains mass/plant) was analysed in F2 generation of 7x7 diallel crosses of rice varieties (without reciprocals). Heritability in broad sense, calculated for each combination separately, is different and depends on the combination at investigated trait. For all combinations together, heritability in broad sense is high for all investigated traits and ranges from 84, 10% for the number of productive tillers/plant, to 97, 59% for the stem height. Heritability in narrow sense has low value for the number of productive tillers/plant (39,19%) only, while calculated values for the other investigated traits range from 55,29% for the number of grains/main panicle to 82,46% for the stem height.
